Our research group just published a study in Nature on how fish biodiversity in U.S. rivers and streams has been changing over the past 27 years (1993–2019). The results show sharply diverging trends depending on historic and changing water temperature. 🧵 rdcu.be/eH0l8

Climate change is reshaping the fish communities of rivers across the US - my commentary in @nature.com to accompany the new study led by @rumschsl.bsky.social rdcu.be/eHY6B 🌍🧪

Climate change is reshaping fish communities in the United States | Nature

Rising temperatures and the introduction of non-native fishes have been linked to rapid changes in fish communities across the United States. Rising temperatures and the introduction of non-native fishes have been linked to rapid changes in fish communities across the United States.

Nature research paper: Diverging fish biodiversity trends in cold and warm rivers and streams

Diverging fish biodiversity trends in cold and warm rivers and streams - Nature

In the past three decades, fish abundance, richness and uniqueness have diverged across cold and warm streams, and the effects on native fish communities of stream warming and increases in introduced fishes have magnified each other.

#lirpaloof Since it's already 2025-04-01 for most of the world ... a slightly updated version of the `celebrate` package: `remotes::install_github("bbolker/bbmisc/celebrate")`. (Description: Celebrate your successes and mourn your failures.) Now supports `htest` objects!

celebrate package:celebrate R Documentation

Audio 'announcements' when printing model summaries

Description:

The only function of this package is to augment the printing of
model summaries with appropriate sound effects based on whether
you have achieved the magical p<0.05 level of significance for at
least one variable (not including the intercept - we have to try
to be a _little_ bit sensible ...)

Details:

Sounds are taken from <http://freesounds.org>

To set an alpha-level different from 0.05, you can specify
‘options(celebrate.alpha = <value>)’

(CC BY 3.0)

• trombone: user kirbydx,

(CC0)

Examples:

## Not run:

m1 <- lm(speed~dist,cars)
m2 <- lm(Income~Population,data.frame(state.x77))
summary(m1)
summary(m2)
## chi-squared test
M <- as.table(rbind(c(762, 327, 468), c(484, 239, 477)))
dimnames(M) <- list(gender = c("F", "M"),
party = c("Democrat","Independent", "Republican"))
(Xsq <- chisq.test(M)) # Prints test summary
boring <- matrix(c(6,5,4,5), nrow = 2)
(chisq.test(boring))
## End(Not run)
